Does anyone know what on earth "0442071010nnn"* is, it doesn't look like an allowable UK phone code, but has just come up on the Caller ID and 1471 (UK Numbers are usually 0115nnnnnnn[etc] and foreign are INTERNAT) and was one of them "Hi this is brenda you have won" [click] numbers.

*Last three numbers deliberatly blocked.

not sure but usually 0044207 I would guess would be a london number
as to why it showed up as a 044 is a strange code though .

Like jasonpaul says it's a London number that for some reason is presenting with the international dialling code. Try googling the number in 0207 or 020 7 format and see what you come up with. Just searching for 0207 1010 brings up a few results, for example a datacomms company and (slightly bizarrely) something that's maybe to do with the Home Office.

Ay, tried that one, nothing come up apart from the data comms companys on the shorter bit. I wonder if any do voip and have cocked there systems up?
